| The objective of the present work was to assess the biomass of Atlantic thread herring (Opisthonema oglin1lm) and the Spanish sardine (Sardinella aurita) in the north area of the Colombian Caribbean sea by means of two acoustic surveys (one in July-August and other in December, 1997). The scientific echosounder used for both surveys was the SIMRAD EK500. Emphasis was made on Atlantic thread herring and Spanish sardine because these small pelagic fish have been the most abundant in previous studies in this area. Systematic sampling using parallel transects perpendicular to the coast was carried out. The transect spacing used was 12 nautical miles. The Elementary Sampling Distance Unit (ESDU) was set in 1 nm. In order to know about the species composition... |
